On one slide, show different images, loaded from a list

[Vera]

Hi David,

well about the "I need you to struggle a bit first so that the later
lesson will "take" " I think I definitely have been struggling a lot
already and trying every single solution I could think of (including
scripts, including nested lists, including nested lists with colon
syntax...). :-)

For the colon syntax by the way, I first thought of this solution too
(well after I tried the first solution in which I naively expected E-
Prime to read out 9 different images out of one list (out of one
column so to say) which is apparently not the case) so I wrote into my
list that my images (all with the syntax [Image] as filename (and yes,
I created an attribute "Image" too) should go to the attribute
[ImageInNestedList:9] in the nested list (which of course also I
created with an attribute ImageInNestedList). But the same problem
here too: E-Prime only reads out 1 image out of this list (so one line
at a time) and then replicates that image 9 times (so yep, I end up
with 9 times the same image on the slide).

So for the moment, the only solutions I see are:

1. Define a certain number of combinations (let's say 200) and just
write them into E-Prime.
2. Write some kind of script
3. Make let's say 200 different images (fixed with the 9 images).

The last one is by the way the solution I am going to use for the
moment (a collegue has some script to create 200 random images in no-
time) as time is running out and we need a "quick and dirty" solution
rapidly. However, I will keep on trying to get this right, because
after the pilote-study, this whole test is supposed to communicate
with our driving simulator (I am not programming this!) so that we can
control some driving task with the secondary task.

So I still need to find a solution!!!

:-)
